From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Should I switch from the older OEM kernel to the newer generic kernel? (lemm.ee)

I am using a Dell Latitude 3420 (Ubuntu 22.04.3) and it uses a slightly older OEM kernel 5.14.0-1048-oem. The generic kernels keep getting upgraded but are never used. The current generic that I have is 6.2.0-26-generic and 5.15.0-79-generic.

So I have 2 questions

  1. Should I leave the kernel as it is? Some threads online say it's better to leave it as it is as an OEM kernel is better for Ubuntu-certified laptops
  2. If I should change the kernel, what would be the best way? I don't want to hard-code the kernel version.
    • If I have issues in the latest generic kernel, I should be able to roll-back to the OEM kernel.

Are there specific bugs vulnerabilities in your current kernel that you want to avoid? There usually isn't much to gain by upgrading kernels, unless you have unsupported hardware or a kernel vulnerability. And if your lucky, the OEM kernel should have bug fixes backported to it anyway.

If you have the generic kernels installed, you should be able to boot them from GRUB/bootloader, try it and see if it all still works?
